Technical field
The utility model relates to the reactor content distribution apparatus in the petrochemical industry, relates in particular to a kind of upstriker gas-liquid distributor.
Background technology
Common gas and liquid mixing streams are through the reactor of beds in the petrochemical industry; Gas-liquid distributor need be set in the reactor gas and liquid are evenly distributed to the whole reactor cross section; Promote the even distribution with heat of reaction that makes full use of of catalyst, avoid occurring the generation of rough sledding such as focus.
Common gas-liquid distributor all is that mixed material from up to down is distributed on the reactor cross-section, for bottom-up upstriker gas-liquid distributor, is difficult to find pertinent literature or disclosed technical scheme at present.
As shown in Figure 1, patent CN2369747Y has announced gas-liquid allotter in a kind of packed bed, comprises distribution plate and distributor, and one or more separate distributors are vertically mounted on the distribution plate.This distributor is applicable to the distributional effects of downstriker gas-liquid, and its structure is complicated, and manufacturing cost is higher.
The utility model content
In order to fill up the technological gap of upstriker gas-liquid distributor in the art, the utility model provides a kind of upstriker gas-liquid distributor.
The design of the utility model is following:
A kind of upstriker gas-liquid distributor comprises distributor pipe 1 and distribution grid 2, and said distributor pipe 1 upper end is communicated with said distribution grid 2 fluids, and said distributor pipe 1 lower end is provided with oblique angle opening 5; Said gas-liquid distributor also comprises baffle plate 3, and said oblique angle opening 5 is connected with baffle plate 3, and said baffle plate 3 hides said oblique angle opening 5; Said distributor pipe 1 tube wall is provided with gas passage 4.The oblique angle opening (5) of said distributor pipe (1) lower end is towards being that initial point is radioactivity and outwards arranges with said distribution grid (2) center.
One group of said distributor pipe 1 vertically is covered with in said distribution grid 2 lower ends, and the angle between said oblique angle opening 5 and the said baffle plate 3 is 30～50 degree.
In the concrete enforcement, said oblique angle opening 5 is 45 degree with the angle of said baffle plate 3.
In concrete arranging is provided with; One group of said distributor pipe 1 is arranged according to square and is covered with said distribution grid 2; Promptly four said distributor pipes 1 surround square shaped cells; 1 group of said distributor pipe comprises many group square shaped cells, is covered with by square shaped cells to whole distribution grid 2, and the spacing of adjacent said distributor pipe 1 is 1.25～5 times of said distributor pipe 1 diameter.
The another kind embodiment that is provided with that arranges is: one group of said distributor pipe 1 is arranged according to equilateral triangle and is covered with said distribution grid 2; Promptly three said distributor pipes 1 surround the equilateral triangle unit; Said distributor pipe comprises many group equilateral triangles unit for 1 group; Extremely whole distribution grid 2 is covered with by the equilateral triangle unit, and the spacing of adjacent said distributor pipe 1 is 1.25～5 times of said distributor pipe 1 diameter.
Among the embodiment, said gas passage 4 is circular gas passage, comprises one deck circular hole gas passage at least; It is arranged in said distributor pipe 1 upper end near distribution grid 2 places, and is 180 degree with the direction of said oblique angle opening 5.
Another kind of embodiment, said gas passage 4 is a grooved hole gas passage, comprises one deck grooved hole gas passage at least; It is arranged in said distributor pipe 1 upper end near distribution grid 2 places, and is 180 degree with the direction of said oblique angle opening 5.
The diameter range of said distributor pipe (1) is DN15mm～DN100mm, and said distributor pipe (1) length range is 150～500mm.Preferably, the diameter of said distributor pipe (1) is DN25mm.
In actual mechanical process, the gas-fluid two-phase mixture material flows from bottom to top, because the covering of baffle plate 3, mixed material can not directly get into distributor pipe 1.Gas is also assembled because of the upwards mobile arrival distribution grid of continued 2 belows that stop that density gently receives baffle plate 3 gradually.Liquid is walked around baffle plate 3 backs and is got into distributor pipe 1.
When Liquid Flow reaches balance, below distribution grid 2, form the gas bed course that a thickness is slightly larger than gas passage, most of distributor pipe is immersed in the liquid.Therefore, gas gets into distributor pipe 1 through gas passage 4, and liquid gets into distributor pipe 1 through distributor pipe 1 lower end.Because distributor pipe 1 length range is 150～500mm, the stable of gas bed course and of the even distribution of gas-liquid material have been guaranteed in reactor cross-section.
In addition, because gas passage 4 is N layer circular hole or 1 grooved hole, the circulation area that when the volume ratio of gas-liquid two-phase fluid changes, can progressively change gas passage guarantees the distributed uniform degree, and operating flexibility of the present invention is big.
Compared with prior art, the beneficial effect that the utlity model has is:
1) uniformity of gas-liquid distribution is high;
2) operating flexibility is big;
3) simple in structure, processing and manufacturing is convenient, reduces investment outlay.
